Actuator Plunger O-ring Installation
1. Install an O-ring (3, Figure 3-5) into the O-ring
groove located at the large diameter end of the
actuation plunger (2).
2. Install a split Glyde ring over the O-ring. (Twist
and squeeze the split Glyde ring into a small cir-
cle before installing to insure a tight fit over the
O-ring).
Assembly of Valve
NOTE: Start with either side (circuit) of the valve and
build that side complete through Step 4 before
starting on the other side (circuit). Be careful to
assemble components into the circuit from which
they were removed.
1. Lightly lubricate the actuation plunger Glyde
ring (3, Figure 3-5).
2. Install the "B1" actuation plunger (2) into the
"B1" circuit. Be careful not to damage or cut the
Glyde ring during installation. Observe the
Glyde ring assembly through the tank port as
the plunger is being installed. (Refer to Figure
3-8) It may be necessary to work the Glyde
rings past the sharp edge in the body to prevent
damage to the seal. Make sure the actuation
plunger is completely seated and bottomed.
3. Repeat Steps 1 through 4 for the "B2" actuation
plunger.
4. Install the plunger return spring (4, Figure 3-5),
regulator springs (5 & 6) and spring seat (7) into
the appropriate circuit. If spring seat does not
seat correctly on top of the control spring, lightly
shake the valve to correctly position the spring
seat.

5. Lightly lubricate the regulator spool (8).
6. Install the regulator spool into the regulator
sleeve (14). The spherical end of the spool
should be at the top of the regulator sleeve. The
top of the sleeve is the end with the smallest
O.D.

NOTE: Check to insure that the spool will slide
smoothly and freely. Replace the entire sleeve
assembly and spool, if the spool does not slide
smoothly and freely.
7. Remove spool from sleeve before installing
sleeve into body.
8. Lightly lubricate the O-rings (10, 12, & 13) on
the regulator sleeve.
9. Install the regulator sleeve assembly into the
correct circuit in the valve. Make sure the spring
seat is correctly seated in the regulator spring
before installing the regulator sleeve assembly.
Push sleeve into bore until sleeve retaining
flange at the base of sleeve contacts the valve
body.
